Although it is not a large population of monumental character, it does not mean that there is nothing to see in Zalduondo. Its pleasant town centre and the richness of its surroundings are well worth a visit. Its main building is the Church of San Saturnino (16-18th century), which is notable for its large six-storey tower with a pyramidal top and its Baroque altarpiece (17th century) designed by Pedro de Ayala. The Hermitage of San Julián has a graceful Romanesque corbel and a Visigothic window on the apse wall.
As an example of civil architecture, the Palace-Museum of Lazarraga-Amezaga stands out, also known as the Palace of the Gizones (Men), 16th century, which has a beautiful plateresque façade on which a spectacular coat of arms is placed, flanked by two large anthropomorphic sculptures. The palace houses the Regional Ethnographic Museum, which is a review of the history, culture and traditions of the area through various artistic and archaeological samples from surrounding places.
Another remarkable building is the Andoin-Luzuriaga Palace, erected in 1683. It has an attractive ashlar stone façade with beautiful examples of forging on its balconies and a large coat of arms over its main entrance. Nowadays it is the residence of the famous Gipuzkoa writer Bernardo Atxaga.
Zalduondo also has several churches and hermitages, built in connection to its role in the Camino de Santiago, which are spread over different parts of the municipality. Among them are the Hermitage of the Holy Spirit, located inside the cave of San Adrián, and the Hermitage of San Julián and Santa Basilisa, from the 12th century, near Aistra. It is also worth visiting its two medieval bridges (Zubizabal and Txaroste) and its natural surroundings on an enjoyable walk.
As a tribute to the illustrious character of Celedón Alzaga, famous for his festivities in Vitoria, the Celedón Monument was erected in Zalduondo, where a fountain flows wine out from on holidays, as it could not be otherwise.
Your visit will be of particular interest if it takes place during the carnival season, as the Carnival of Zalduondo is considered to be the most interesting in Álava from an ethnographic point of view, attracting numerous visitors every year.
